The present investigation has been undertaken with aim to formulation and evaluation of etoricoxib gel with different gelling agent and different penetration enhancer. Etoricoxib is highly selective cyclooxygenase-2 (COX-2) inhibitor. In this present study gel with carbopol, HPMC and Na-CMC as gelling agent prepared with different penetration enhancer like propyl glycol, oleic acid. Menthol oil. Formulation were evaluated for pH, stability study, spreadibilty, extrudabilty, bioadhesive (ex-vivo), skin irritation, viscosity, appearance and In-vitro drug diffusion. The formulation of Etoricoxib topical gel was prepared using carbopol, HPMC and Na-cmc in three batches A, B and C. With the consideration of all formulation characteristic and parameter we selected batch-A formulation for further study of anti-inflammatory and anti-analgesic activity. It was concluded that the Etoricoxib gel formulation containing carbopol with increase concentration of propyl glycol 10% and 2% oleic acid (OA) was suitable for topical application and it shows comparable result with market product and shows much better result of formulation, anti-inflammatory and anti-analgesic activity.
